To all whom it may concern:

Be it known that l, Eiiisnmrrrr ltnrnnsrmn, a subject of the Republic oflPrussia, German Republic, and resident of Blasewitz, near Dresden, have invented a newand useful lmprovement in Spring Button or Pressure Fasteners, of which the following is a spec ification.

The present invention relates toe separable fastener for garments or dresses comprising a stud member and a socket member and commonly linown as press or snap buttons provided with binding springs arranged within the plate of the socket member.

Fasteners of the kind mentioned before of circular or rhomboidal shape are known already.

The present invention has for its object a press or snap button in which a socket member closed on its periphery is provided and the stud member and the socket member are of considerable length in comparison with their width resulting in bodies of an eX- tended or longish form. The arrangement of the garment-fastener of this kind ensures the advantage that its dimensions in length are increased without in any way necessitating an increase of its dimensions in width. Another advantage of such a garment fastener can be seen in the fact that, in comparison with using several separate press or snap-buttons fastened to a garment one above another or asideof each other, said fastener is a very firm and pra ,tical one, in as much as it is capable to most ui'iiformly resist any pull acting on the total length of the fastener in such a manner that pleats cannot be formed Within the garment near thefastener, on the contrary it will constantly maintain its original smoothness.

The accompanying a sheet of drawings shows a fastener constructed in accordance with the invention- Fig. 1 represents a plan view and Fig. 2 a front plan view of the stud-member, F 3 and a similar plan views of the socket member. Figs. 5 and 6 are sections according to line 5-5 of Fig. l and to line 6--6 of Fig. 3. Fig. 7 is partly a longitudinal elevation and partly a longitudinal section, showingsaid two members fastened or locked together and Fig. 8 a transverse-section according to line 8-8 of side portions 6 Fig. 7. Like letters of reference indicate corresponding parts in the several figures.

The stud or male member a is provided with a-"straight and hollow ridge a of considerable length in comparison with its width, the sides of said ridge being inclined. The side portions c of the stud or male member are pierced with holes for sewthat they may touch or meet the end portions of the ridge a inserted into the socketmember 6, as clearly seen in the righthand part of Fig. 7. The side portions 6 are provided with holesb for sewing to the other part of the garment.

in looking both members a and I) together, the ridges ca and b are situated one in another on their entire length greatly extended in comparison with their width and the inner ridge c is fastened by the binding springs c c projecting through the ridge 6 and resting against the ridge a as clearly seen from the righthand side of Fig. 7.

A garment-fastener arranged according to the present invention provides for a firm closure of garments and is highly resistant against any pull acting on. it, so that the material of the garment remains fully smooth and without pleats.
